Systems and methods for optimizing transaction conversion rate using machine learning

ABSTRACT

A method for optimizing transaction authorization conversion rates using machine learning includes retrieving payment transaction parameters and authorization results for a plurality of past payment transactions from a database, generating a transaction success model comprising authorization success factors for each of a plurality of payment transaction parameters using a machine learning training phase based on the retrieved payment transaction parameters and authorization results, receiving, at an acquirer processor, a payment transaction from a merchant, modifying one or more parameters of the payment transaction according to the generated transaction success model, and submitting the modified payment transaction to a financial institution for processing.

TECHNICAL FIELD

Various embodiments of the present disclosure relate generally to the field of electronic transaction processing and, more particularly, to optimizing authorization requests for higher transaction conversion rates.

BACKGROUND

Electronic transactions and networks are used for a great number of purchases and sales between merchants and bank card holders. A normal bank card transaction may involve a number of parties, including an account holder who possesses a card, a merchant, an acquirer processor, an issuer processor, an issuer financial institution, and a card association network. Millions of such transactions occur daily at merchants using a variety of payment card types, such as credit cards, debit cards, prepaid cards, and so forth. A transaction based on account information received from an account holder may be declined for a number of different reasons, such as insufficient funds, card expiration, expired account information, or a variety of other occurrences. However, additional factors, such as the presence or absence of some items of account information, may also affect the rate of acceptance, or conversion, of payment transactions. Declined transactions may lead to a variety of undesirable outcomes for the merchant and the account holder. Conventional methods for submitting electronic transactions may submit such transactions according to factors specific to the acquirer processor or to the merchant, but do not consider factors that might be shown to affect transaction conversion in past transactions.

The present disclosure is directed to overcoming one or more of these above-referenced challenges.

DETAILED DESCRIPTION OF EMBODIMENTS

While principles of the present disclosure are described herein with reference to illustrative embodiments for particular applications, it should be understood that the disclosure is not limited thereto. Those having ordinary skill in the art and access to the teachings provided herein will recognize additional modifications, applications, embodiments, and substitution of equivalents all fall within the scope of the embodiments described herein. Accordingly, the invention is not to be considered as limited by the foregoing description.

Various non-limiting embodiments of the present disclosure will now be described to provide an overall understanding of the principles of the structure, function, and use of systems and methods disclosed herein for the scheduling of transaction payment requests.

For simplicity, the description that follows will be provided by reference to a “payment vehicle,” which generally refers to any type of financial alternative to currency. As is to be clear to those skilled in the art, no aspect of the present disclosure is limited to a specific type of payment vehicle. Therefore, it is intended that the following description encompasses the use of the present disclosed techniques with many other forms of financial alternatives to currency, including credit cards, debit cards, smart cards, single-use cards, pre-paid cards, electronic currency (such as might be provided through a cellular telephone or personal digital assistant), and the like. Payment vehicles may be traditional plastic transaction cards, titanium-containing, or other metal-containing, transaction cards, clear and/or translucent transaction cards, foldable or otherwise unconventionally-sized transaction cards, radio-frequency enabled transaction cards, or other types of transaction cards, such as credit, charge, debit, pre-paid or stored-value cards, or any other like financial transaction instrument. A payment vehicle may also have electronic functionality provided by a network of electronic circuitry that is printed or otherwise incorporated onto or within the payment vehicle (and typically referred to as a “smart card”), or be a fob having a transponder and an RFID reader, or may operate as a mobile wallet or by near field communication (NFC).

As described above, declined transaction payment requests may lead to undesirable outcomes, and associated increased costs, for merchants and account holders. Thus, the embodiments of the present disclosure are directed to improving (i.e., increasing) the successful authorization of transaction payment requests.

In accordance with one or more embodiments, and as described in more detail below, an acquirer processor may maintain a database of past transactions and the associated authorization results. Analysis of these transaction results by statistical methods or other means may be used to determine patterns of acceptance or denial of transaction payment requests based on factors associated with the transactions, including, for example, presence of a billing address, presence of a card verification code (CVV), the merchant categorization code (MCC), presence of an expiration date, etc. The transaction may be modified with respect to these factors, as determined at least in part by such an analysis of historical authorization success rates. According to one or more embodiments, a modified authorization request may be submitted to the payment network.

One or more examples of these non-limiting embodiments are illustrated in the selected examples disclosed and described in detail with reference to FIGS. 1-7 in the accompanying drawings. Those of ordinary skill in the art will understand that systems and methods specifically described herein and illustrated in the accompanying drawings are non-limiting embodiments. The features illustrated or described in connection with one non-limiting embodiment may be combined with the features of other non-limiting embodiments. Such modifications and variations are intended to be included within the scope of the present disclosure.

FIG. 1 depicts a block diagram of an example payment environment 100 for optimizing transaction authorization conversion rates. In the example payment environment 100, a payment vehicle 126 (e.g., a credit card) may be issued to an account holder 113 by an issuer financial institution 114. Issuer financial institution 114 may be any of a variety of financial institutions that is capable of issuing a payment vehicle to an account holder. Payment vehicle 126 may be used to pay a merchant 116 for a purchase transaction at a merchant point of sale (POS) device 118. Merchant POS device 118 may be any device that facilitates receipt of a payment vehicle for payment of a purchase, such as for example, a POS terminal or a web interface. Further, merchant 116 may be any type of merchant or service provider, such as, for example, a brick-and-mortar merchant, an online merchant, a mobile merchant, a kiosk, or any other type of merchant or device configured to receive payment cards, or electronic or mobile wallets, from account holders as a form of payment.

POS device 118 may be configured to interact with payment vehicle 126 to obtain account information about a consumer account affiliated with account holder 113. As shown in the depicted callout of POS device 118, in one or more embodiments, POS device 118 may include a memory 167 coupled to processor 151, which may control the operations of a reader 163, an input device 153, an output device 165, and a network interface 161. Memory 167 may store instructions for processor 151 and/or data, such as, for example, an identifier that is associated with merchant account 112.

In one or more embodiments, reader 163 may include a magnetic strip reader. In one or more embodiments, reader 163 may include a contactless reader, such as, for example, a radio frequency identification (RFID) reader, a near field communications (NFC) device configured to read data via magnetic field coupling (in accordance with ISO standard 14443/NFC), a Bluetooth transceiver, a Wi-Fi transceiver, an infrared transceiver, a laser scanner, and so forth.

In one or more embodiments, input device 153 may include key buttons that may be used to enter the account information directly into POS device 118 without the physical presence of payment vehicle 126. Input device 153 may be configured to provide further information to initiate a transaction, such as, for example, a personal identification number (PIN), password, zip code, etc., or in combination with the account information obtained from payment vehicle 126. In one or more embodiments, output device 165 may include a display, a speaker, and/or a printer to present information, such as, for example, the result of an authorization request, a receipt for the transaction, an advertisement, and so forth.

In one or more embodiments, network interface 161 may be configured to communicate with acquirer processor 122 such as, for example, via a telephone connection, an Internet connection, or a dedicated data communication channel.

In one or more embodiments, the instructions stored in memory 167 may be configured at least to cause POS device 118 to send an authorization request message to acquirer processor 122 to initiate a transaction. POS device 118 may or may not send a separate request for the clearing and settling of the transaction. The instructions stored in memory 167 also may be configured to cause POS device 118 to perform other types of functions discussed in this description.

In one or more embodiments, POS device 118 may have fewer components than those illustrated in FIG. 1. For example, in one or more embodiments, POS device 118 may be configured for “card-not-present” transactions; and POS device 118 may not have a reader 163. In one or more embodiments, POS device 118 may have more components than those illustrated in FIG. 1.

During a purchase event, merchant POS device 118 may send an authorization request 120 for the purchase transaction to acquirer processor 122 that processes payment vehicle transactions for merchant 116. Additional intermediary entities, such as one or more payment gateways, may assist with the handling and routing of authorization request 120 or other related messaging. For the purposes of illustration, such intermediary entities may be considered part of acquirer processor 122. Authorization request 120 may include identifying information from payment vehicle 126, such as a BIN number, an expiration date, and a first and last name of the account holder, for example. Authorization request 120 may further include identifying information from the purchase, such as an amount and identifying information from merchant POS device 118 and/or merchant 116, for example.

In one or more embodiments, payment vehicle 126 may be used to establish a recurring billing arrangement between account holder 113 and merchant 116. An initial transaction may allow merchant 116 to store account information that may be used for subsequent billing events. The account information may be stored in a cards-on-file storage 136. For example, the purchase event illustrated in FIG. 1 may be associated with a subscription, membership plan, installment payment plan between merchant 116 and account holder 113, and so on. For subsequent transactions, merchant 116 may access cards-on-file storage 136 to retrieve the relevant account information. The subsequent transactions may not require direct involvement from account holder 113. In one or more embodiments, account holder 113 may trigger the subsequent transaction, but may not provide payment vehicle 126 to merchant 116, as merchant 116 may access the cardholder's account information in cards-on-file storage 136.

A payment processing computing system 124 at acquirer processor 122 may receive authorization request 120 from merchant 116. Payment processing computing system 124 may translate authorization request 120, if necessary, and may provide authorization request 120 to a payment network 142. Payment network 142 may be, for example, a network of a credit card association affiliated with payment vehicle 126. Nonlimiting examples of credit card associations include VISA, MASTERCARD, DISCOVER, and AMERICAN EXPRESS, and so on. Authorization request 120 then may be provided to a payment processing computing system 128 at an issuer processor 130. In response to receiving the authorization request, and based on the type of payment vehicle 126, payment processing computing system 128 may provide authorization request 120 to issuer financial institution 114. Using information from authorization request 120, issuer financial institution 114 may associate the purchase transaction with an account 131 of account holder 113 held by issuer financial institution 114. Issuer financial institution 114 then may send an authorization response 132 which may either approve or deny the transaction. Authorization response 132 may be provided to payment processing computing system 128 at issuer processor 130 and then provided to payment network 142. Authorization response 132 then may be provided to payment processing computing system 124 at acquirer processor 122. Upon receiving authorization response 132, payment processing computing system 124 may send either an approval message or a denial message to merchant POS device 118 to complete the purchase transaction. If the purchase transaction is approved, it may be posted to account holder's account 131 and reconciled later with account holder 113 and merchant 116.

Transaction records may be stored in one or more locations within system 100. In one or more embodiments, the transaction record may be stored within a transaction data database 134 of acquirer processor 122. The transaction data may be received by transaction data database 134 from various sources, such as merchant POS device 118, merchant 116, acquirer processor 122, and so on. A plurality of transaction parameters associated with the purchase transaction may be stored in each transaction record, which may generally be used for settlement and financial recordkeeping. While the transaction parameters stored in each transaction record may vary, example transaction parameters may include, without limitation, account number, card number, payment vehicle information, product information (such as product type, product serial number, and so forth), loyalty account information, merchant information, transaction amount, response code, transaction date, transaction time, whether the transaction was a “card present” transaction, and so on.

FIG. 2 depicts a dataset of processing results, according to one or more embodiments. Dataset of processing results 134 may include historical transaction information that may be processed and analyzed in order to optimize transaction conversion rates, as shown in FIG. 3 based on, for example, an analysis of trends and/or correlations. Dataset 134 may include transaction parameters 220 such as, for example, a billing address 222, a card verification value (CW) 224, a payment processing network 226, a payment vehicle expiration date 228, a payment vehicle issuer token 230, a merchant classification code (MCC) 236, and additional parameters 238. Dataset 134 may also include an authorization result 240, which may indicate whether the particular combination of transaction parameters 220 led to an authorization (232) and a reason response code (RRC) related to the authorization result (234). Further, while dataset of processing results 134 may include many different transaction parameters 220, in some embodiments only a subset of the parameters may be used for optimizing transaction authorization conversion rates.

FIG. 3 depicts a block diagram of an example process logic flow for optimizing transaction authorization conversion rates, according to one or more embodiments. As shown in FIG. 3, a process for optimizing transaction authorization conversion rates may include identifying factors for authorization of transaction requests to produce a database of transaction requests 134. For example, such identification may include applying data science methods 310 to database of transaction requests 134. However, other methods may be used such as machine learning, etc. Database of transaction requests 134 may further include information produced by performance manager 355 based on factor success data, possibly in conjunction with a process or generating and updating factor success data 360, such as learning engine 320. Learning engine 320 may process transaction data stored in transaction request database 134 in order to generate factor success data 360. For example, learning engine 320 may perform a training phase to process the transactions contained in the dataset of processing results in order to tune a transaction success model, a validation phase to determine how well the transaction success model provides improved transaction conversion, and an application phase to apply the transaction success model to the parameters of a payment transaction. Learning engine 320 may operate under one or more algorithms for machine learning such as, for example, decision tree learning, association rule learning, artificial neural networks, deep learning, inductive logic programming, support vector machines, clustering, Bayesian networks, reinforcement learning, representation learning, similarity and metric learning, sparse dictionary learning, genetic algorithms, and rule-based machine learning, etc. Learning engine 320 may implement supervised learning, unsupervised learning, or semi-supervised learning. Factor success data 360 may aggregate test and control groups. Data stored in factor success data 360 may be used to determine the effectiveness of optimizing transaction requests, such as by comparing results for optimized transactions (test transactions) and non-optimized transactions (control transaction). Such a determination may be specific to particular factors employed for optimization of test transactions. Factor success data may further include measurement, for example, at the level of the specific issuer and account range (generally associated with a card product of a particular issuer), of the sensitivity of a factor. That is, an assessment of whether a manipulation (inclusion, exclusion, alteration) of a factor resulted in an improvement or decrease in the rate of authorization approvals at that issuer/account range. Performance manager 355 may automatically calibrate optimization factors employed by rules engine 345 through analysis of factor success data 360 and transaction scenarios stored in dataset of processing results 134. Performance management may include, for example, the modification of prior rules based on continuing assessment of the results from transactions sent to the issuer/account range. It may include and take into account negative results besides the authorization denial, such as an increase in the rate of chargebacks or fraud alerts generated by the issuer. These negative effects may occur, for example, even if the authorization is approved.

A merchant, such as merchant 116 depicted in FIG. 1, may submit a transaction request, such as authorization request 120 depicted in FIG. 1, to acquirer processor 122. The transaction request may be interpreted by rules engine 345 of the acquirer processor based on the database of transaction requests and the factor success data. The transaction request may be re-formatted by an authorization formatting service, such as authorization formatting service 350 and 330 prior to being submitted to a payment network. Re-formatting of transaction requests may be performed, for example, in batch, in a queue of transaction requests, asynchronously, or in real time as a managed service, such as managed service 330 depicted in FIG. 3, etc. The transaction processing by the acquirer processor may also include a validation and reporting functions, such as A/B testing and reporting of authorization success metrics 340.

FIG. 4 is a flow chart depicting an example process for optimizing transaction authorization conversion rates, according to one or more embodiments. As shown in FIG. 4, at operation 405, acquirer processor 122 may generate factor success data, such as factor success data 360 depicted in FIG. 3, from a dataset of processing results, such as transaction database 134 depicted in FIG. 1. The factor success data may be generated using a machine learning algorithm executed by a learning engine, such as learning engine 320 depicted in FIG. 3. For example, the learning engine may execute a training phase in which the learning engine may process the transactions contained in the dataset of processing results in order to tune a transaction success model that may comprise the weighted factors to be stored in the factor success data. At operation 410, acquirer processor 122 may receive a payment transaction from a merchant, such as merchant 116 depicted in FIG. 1. The payment transaction may include, in addition to a transaction amount, primary account identifier, customer identification, etc., for example, a billing address, a card verification value (CVV), a payment processing network, a payment vehicle expiration date, a payment vehicle issuer token, a merchant classification code (MCC), and additional parameters. At operation 415, acquirer processor 122 may determine parameters of the payment transaction, such as authorization request 120 depicted in FIG. 1. Determining the parameters of the payment transaction may include identifying parameters that are not present in the transaction, such as the CVV, expiration data, billing address, etc. At operation 420, acquirer processor 122 may process one or more parameters of the payment transaction to improve the transaction authorization conversion rate. For example, the learning engine may execute an application phase in which the transaction success model is applied to the parameters of the payment transaction to determine which parameters of the payment transaction, if any, may be modified to improve the transaction authorization conversion rate. At operation 425, acquirer processor 122 may modify the parameters of the payment transaction according to machine learning application phase. At operation 430, acquirer processor 122 may submit the modified transaction for processing by an issuer processor, such as issuer processor 130 depicted in FIG. 1. At operation 435, acquirer processor 122 may receive a transaction authorization result from the issuer processor. At operation 440, acquirer processor 122 may add the transaction authorization result and the parameters of the payment transaction to the dataset of processing results. The process may then resume at operation 405 in order to process subsequent transactions.

FIG. 5 depicts a block diagram of an example process flow for optimizing transaction authorization conversion rates, according to one or more embodiments. A payment transaction 506 may be received from a merchant 502 by an acquirer processor 508. Payment transaction 506 may be based on account information 504 maintained by merchant 502, or elsewhere, as may be appropriate. Payment transaction 506 may include typical transaction data, such as, for example, an amount, an account identifier, a billing address, a card verification value (CVV), a payment vehicle expiration date, a payment vehicle issuer token, a merchant classification code (MCC), etc. At least some of the transaction data transmitted in the payment transaction may include data that was originally received by merchant 502 during an initial payment transaction originating with a payment vehicle and stored in a cards-on-file storage 136, for example. A payment processing computing system of acquirer processor 508 may determine the card association that is affiliated with the payment transaction 506 (e.g., VISA, MASTERCARD, and so forth), to determine the proper processing channels for the transaction such as, for example, a payment processing network.

Acquirer processor 508 may transmit an authorization attempt or transaction request 514 to a payment network, which in turn may transmit transaction request 516 to an issuer financial institution 518. Issuer financial institution 518 may approve or reject the authorization request based on a status of a financial account 530 associated with the transaction or cardholder, or other factors, such as, for example, the presence or absence of a billing address, the presence or absence of a card verification value (CVV), the presence or absence of a payment vehicle expiration date, the presence or absence of a payment vehicle issuer token, a merchant classification code (MCC), a selection of a payment processing network, etc. Generally, all authorization requests include an MCC, however some issuing banks view certain MCCs as riskier than others and therefore the selection of which MCC to include in the authorization requests—assuming the merchant qualifies for more than one—can influence the approval. Acquirer processor 508 may communicate the authorization result of transaction request 516 to merchant 502 by, for example, an authorization response 507. Financial account 530 can be any suitable account, such as a DDA account, a gift card account, a prepaid account, or any other type of account that can be linked to or accessed by payment vehicle. The available account balance of financial account 530 may vary over time as the account holder withdraws funds and deposits funds. Transaction requests may be rejected, for example, for reasons associated with financial account 530, such as non-sufficient funds, out-of-date account information, parameters provided with or absent from the transaction request etc. Acquirer processor 508 may store factors associated with transaction request 516 in dataset of processing results 134 that may be used to determine a likelihood of authorization or conversion for subsequent transaction requests. As described above with respect to FIG. 2, factors associated with transaction request 516 may include, for example, billing address 222, card verification value (CVV) 224, payment processing network 226, payment vehicle expiration date 228, payment vehicle issuer token 230, merchant classification code (MCC) 236, additional parameters 238, reason response code (RRC) 234, and so forth. In accordance with one or more embodiments, acquirer processor 508 may, as discussed in greater detail below in reference to FIG. 6, include performance manager 355, learning engine 320, and rules engine 345, to process payment transaction 506 based on transaction data 134 and factor success data 360. Acquirer processor 508 may further include an authorization formatting engine 350 to appropriately modify payment transaction 506 based on the processing of payment transaction 506.

FIG. 6 depicts a block diagram of an example process logic flow and modules for optimizing transaction authorization conversion rates, according to one or more embodiments. As shown in FIG. 5, acquirer processor 508 may receive payment transaction 506. As shown in FIG. 6, payment transaction 506 may include transaction data such as, for example, a billing address 622, a card verification value (CVV) 624, a payment processing network 626, a payment vehicle expiration date 628, a payment vehicle issuer token 630, a merchant classification code (MCC) 636. Payment transaction 506 may include additional parameters not shown in FIG. 6. Rules engine 345 of acquirer processor 508 may take in the transaction data for processing. Such processing may include querying dataset of processing results 134 for other potentially corresponding transactions. Factor success data 360 may be generated using a machine learning algorithm executed by learning engine 320. For example, learning engine 320 may execute a training phase in which the learning engine may process the transactions contained in dataset of processing results 134 in order to tune a transaction success model that may comprise the weighted factors to be stored in the factor success data. Rules engine 345 may further read factor success metrics from factor success data 360. Based on the corresponding transaction data received from dataset of processing results 134 and the factor success metrics from factor success data 360, rules engine 345 may invoke learning engine 320 to execute an application phase in which the transaction success model is applied to the parameters of the payment transaction to determine whether the likelihood of obtaining authorization for payment transaction 506 from issuer financial institution 518 may be improved by altering the presentation of one or more aspects of the transaction data. For example, rules engine 345 may, through the application phase of learning engine 320, determine that presentation of payment transaction 506 without billing address information may improve the likelihood of obtaining authorization. In particular, transaction data received from dataset of processing results 134 and the factor success metrics from factor success data 360 may indicate that the issuer financial institution 518 may issue two responses: one indicating overall approval or denial, and one indicating whether a supplied billing address matches a billing address on file with the issuer financial institution 518. If issuer financial institution 518 is known to authorize transactions lacking a billing address and deny transactions having a mismatched address, then presenting payment transaction 506 without billing address 622 may improve the likelihood of obtaining authorization. Similarly, transaction data received from dataset of processing results 134 and the factor success metrics from factor success data 360 may indicate that omitting CVV 624 or expiration date 628 when presenting payment transaction 506 may improve the likelihood of obtaining authorization. In addition, a merchant may qualify for multiple different MCCs based on the nature of the businesses conducted by the merchant. Transaction data received from dataset of processing results 134 and the factor success metrics from factor success data 360 may indicate that one of the available MCCs may have a greater likelihood of obtaining authorization. Rules engine 345 may, accordingly, present payment transaction 506 with the MCC with the greatest likelihood of obtaining authorization. Likewise, transaction request 506 may have multiple payment networks 532 available for submission to issuer financial institution 518 for processing. Transaction data received from dataset of processing results 134 and the factor success metrics from factor success data 360 may indicate that one of the available payment networks 532 may yield a greater likelihood of obtaining authorization. Rules engine 345 may, accordingly, select the payment network with the greatest likelihood of obtaining authorization. Finally, some payment vehicles may have transaction tokens available associated with prior authorization of payment transactions or including encrypted payment or authorization credentials. Presentation of payment transaction 506 with such a token may improve the likelihood of obtaining authorization. Where transaction data received from dataset of processing results 134 and the factor success metrics from factor success data 360 indicate that presentation of a token may improve the likelihood of obtaining authorization, rules engine 345 may include an available token with transaction request 506.

Upon completing the processing of payment transaction, rules engine 345 may invoke authorization formatting engine 350 to appropriately modify payment transaction 506 based on the processing of payment transaction 506. Authorization formatting engine 350 may generate a modified transaction request 514 to be submitted to issuer financial institution 518 by way of payment network 514.

The processes described herein may be performed on or between one or more computing devices that are specially configured to perform the processing described herein. Referring now to FIG. 7, an example computing device 700 is presented. A computing device 700 may be, for example, a server, a computing device that is integrated with other systems or subsystems, a mobile computing device, a cloud-based computing capability, and so forth. The computing device 700 can be any suitable computing device as would be understood in the art, including without limitation, for example, a custom chip, an embedded processing device, a tablet computing device, a POS device 118, a payment processing computing system 124, a payment processing computing system 128, a personal data assistant (PDA), a desktop, a laptop, a microcomputer, a minicomputer, a server, a mainframe, or any other suitable programmable device. According to one or more embodiments, a single component can be replaced by multiple components and multiple components can be replaced by a single component to perform a given function or functions. Except where such substitution would not be operative, such substitution is within the intended scope of the one or more embodiments.
